Valve Stem Seals & Locks

Protect your engine from oil leakage and maintain combustion efficiency with premium valve stem seals. These seals control oil flow to the valve stems, preventing excessive oil consumption, smoke, and fouled spark plugs.

At SBX Performance, we carry high-temperature Viton, PTFE, and OEM-style seals engineered for performance and longevity. Upgrading to quality valve stem seals ensures better lubrication control, reduced wear, and extended engine life — even under high boost or track conditions.

Pair with valve guides, springs, and retainers for a complete cylinder head rebuild that delivers both reliability and performance.
